Hi folks, I want to share with you a product that my team and I have been working on for the past years to help breaking into engineering, and specifically, robotics easier for everyone.
We launched the first CYOBot last year as an open-source legged robot called CYOCrawler. It featured a...
Hello Everyone, I want to make a Buck/Boost converter having a range of 50V-450V of Input and Output of 230V.
I want to ask that i have to use a dedicated IC or I should use a Microcontroller. Because I was going to make a Solar Inverter(1Kw,5Kw). I was going to use ESP 32 because it has many...
Hi group. I'm considering building a AM/FM/SW radio using the Skyworks Solutions SI4844-B20-GU. In reviewing the pin information, there are several abbreviations that aren't clear in what they are and what they are meant to do. These are RESET, SDIO, SCLK, IRQ (all to MCU) and LNA_EN...
Please consider some professional embedded system with 16-bit microcontroller.
I know embedded software build tools report program flash memory usage. I think they also report RAM usage but do they report maximum RAM usage?
Build tools may not know how much heap will be used during...
Hi there,
I have ask how can I bypass the touch button on fan Sencor SFE 2340WH, please? I want to of/off fan with smart momentary switch. Below is componets names, maybe with reading errors and photos of con board. Thank for all suggestions.
PS: The best solution will be if i will be able to...

Fuel economy ECU in a truck is experiencing Flash (stored program flash) ECC Error. Link to microcontroller manual for this ECU is:
https://www.nxp.com/docs/en/data-sheet/MC9S12GRMV1.pdf
The problem was duplicated on a bench.
How to recover from Flash ECC Error? In Flash ECC interrupt...
Hello all, I just had a general question and if this has been asked I am apologize in advance lol, I would like to have a circuit built that I can attach a flex sensor to and have it control a motor output, I have already made a circuit with an Arduino but I was hoping for a very small PCB...
EPS Bench setup we are thinking about: Torque Angle Sensor (TAS) will be emulated by PIC microcontroller. Emulated TAS will be connected to EPS ECU's Single Edge Nibble Transmission (SENT) bus.
Our strategy in getting started with EPS Bench testing: Use PIC microcontroller to apply...
Hello,
I am new to this forum community but I need your help.
We are starting on a new project to construct a two lane multifunctional mini bowling machine (small scale). The two machines will be controlled using a single microcontroller for the motors, switches and sensors, together with a...
Please consider commercial vehicle equipped with EPS ECU and other ECUs such as Antilock brake system (ABS), engine, transmission, Body Control Module (BCM), etc.
I would like to come up with tests for testing EPS on adverse road conditions such as wet or icy pavement for vehicle stability...
Consider a commercial truck. The Electronic Brake Systems (EBS) ECU receives following message from some other ECU. Please explain this message. From where does some other module acquire the Suspect Parameters Number (SPNs) to send to EBS ECU. What does EBS do with the SPNs it receives?
Hi Folks,
just completed a course on creating a webserver using an Arduino Uno which allows for remotely monitoring and controlling actuators. This also includes visualizing the sensor data on really cool looking animated dials... Based on what I've learned (and I really learned a lot), I...
Please consider Active Steering Assist Electronic Control Unit (Steering ECU) used in a commercial truck. It has Lane Keep Assist (LKA) function, Cross-wind compensation, and Road crown compensation.
This ECU is composed of a camera input, and driver outputs to control the torque overlay...
Please consider steering electronic control unit (ECU). It has 6-pin CAN connector.
CAN L pin is connected to another CAN L pin in this 6-pin connector.
CAN H pin is connected to another CAN H pin in this 6-pin connector.
What are the reasons for above connections?
Please consider CAN communication network in a heavy vehicle:
Steering Electronic Control Unit (ECU) has CAN 2.0B. It doesn't have J1939 stack.
All other ECUs in this network are implemented with J1939 stack.
Can CAN 2.0B coexist with J1939?
What code changes are needed in steering ECU and...
Consider an Electronic Control Unit (ECU) mounted in a vehicle. Let's say this ECU has Three CAN channels as follows:
CAN 1
CAN 2
CAN 3
Do these Three CAN channels have to be on different CAN networks? Another words, for example, CAN 1 and CAN 2 are never on the same CAN network?
A
It...
I am developing IOT based applications mostly using ESP-12E/F mostly for domains like smart agriculture, smart garage etc, I had experimented initially and had been using Google IOT. Wanted suggestion that is not dependent on any cloud like currently and will incur charges as well after certain...
A typical Electronic Control Unit(ECU) performs Open Circuit(OC), Short to Ground(STG), and Short to Battery(STB) Diagnostics on selected internal and external pins in the ECU.
For example, consider a external output pin. There is a wire connected from this pin to somewhere else. If this wire...
UPDATE: If you want to skip the full history of progress/discussion and just see the current state of the project, then take a look at it on GitHub: https://github.com/UselessPickles/diamondtel-m92-bluetooth
UPDATE 2: I've entered "phase 2" of this project, attempting to fit my entire project...
How do Gateways function to enable over-the-air (OTA) firmware updates for the different electronic control units (ECUs) within the car. Please summarize OTA flashing through gateway to ECU that gets flashed.
Hello all,
I have a MINI Cooper S tachometer and would like to control the unit via a microcontroller. I have worked with microcontrollers before but have not done anything yet with car electronics.
Any ideas on how I could find any pinout, schema, or datasheet to this device?
Can someone help with mikro c coding of a 6digit countdown timer that include button functionalities such as start/stop, incresse button for setting the timer for minute and hour digit using just pic16f877A?
I used the following proteus design and Mikro c code to build a 6 digit 7segment count down timer using pic16f887A and ic 4026
The proteus design is named Zacch in the attached file and the mikro c is in the code tag. the issue am having is that my proteus simulation isn't working as it...
Hello all, this is one of my first electronic schematics and I'm trying to make sure everything looks good (electrically) before I order board and components. Another set of eyes on this to criticize and give constructive feedback would be great and point out any issues or mistakes my circuit...
Consider a typical autonomous embedded Steering Control Module. This controller is mounted in a Commercial Truck. It assists in keeping the vehicle in it's lane.
During transition to sleep mode, real camera calibration data is written from RAM to NVM. This data written to NVM is corrupted...
